When I run my cards in CrossfireX CCC show that there is some gpu load on the 2nd card when I play games but GPU-z show that the 2nd card is idle (0% GPU load). But the thing that bothers me is that the 2nd card temperature never rises, is this normal for a crossfire system?

Ok so the monitors was not the problem, but now im even more . I reinstalled my ATI drivers hoping it will fix the problem but what I discovered in the proses was that when I enable Catalyst AI my Crossfire works fine, when it is disabled CF doesn't work, but GPU-z detects Crossfire as enabled. Now this is a problem because when you enable Catalyst AI you get this weird bars and stuf on your screen witch spoils everything. Any one got an idea what is going on.

Catalyst AI must be enabled for CrossfireX to work. As far as the bar flickers, in Cat AI, have you tried standard or advanced?

It is definitely drivers tho, but you also have to take into consideration, some 3d applications and games do not totally agree with crossfire either. Post a screenshot of "All Settings" in CCC, maybe together all of us can possibly determine problem. May even be a bad crossfire bridge.

Upon looking at the power supply specs and reading a few reviews it looks like you may be underpowering the cards. From here out you can try and test each card in single use, if that comes back ok the only thing I can say is this or bad drivers. Sorry man.

Well I think the power supply is fine, some of ATI certified power supplies is 550W. I have swoped the cards and they run fine on their own, so it isn't a defective card. I contacted AMD support will see if they know any thing on this issue, I hope they don't follow the same root as Nvidia's support, blaming it on the power supply and with the next drivers your problems are gone .
